About Guillaume

How I can help you:

If you are aSaaS or B2B companywith key account development challenges, I can help you structure your key account approach, maximize customer value, and secure lasting relationships.

If you are developing animpact projector an innovative initiative requiring the involvement of public, private, or academic stakeholders, I can help you structure and activate sustainable partnerships to scale your project.

Who I am:

After several years supporting the growth of startups, and 3 years managing the development of the NGO Boomforest, I am now available for new freelance missions.

My background has led me to work in very different contexts, with one common thread: growing projects.

On the business side, I have:

→ Launched and developed international markets (Canada, France, Netherlands)
→ Supported startups in their early growth phases
→ Managed and developed client accounts in a SaaS environment

On the NGO side, I have:

→ Managed impact projects for urban ecological transition from A to Z
→ Developed public, private, and academic partnerships
→ Coordinated complex projects involving multiple stakeholders
→ Contributed to structuring and growing a rapidly expanding organization

Today, I want to bring this dual experience to new teams, particularly in the areas of:

• Account Management
• Inbound Sales & Closing
• Early-stage Sales Structuring
• Partnership Development

I am particularly comfortable in international, remote environments, and with teams under construction.

I work in a scale-up startup and it's a pleasure to work with Guillaume. Positive, professional, and proactive, he quickly understood our market structure and was able to engage with our clients. We'll do it again very soon for our next need! I recommend him.
